Been using the Ox now since 2015, so decided I should move on to C-Beam :-)
DazTheGas published a new build:
Read more about this build...
Love the video!
Finally uploaded Part 1 of the build somewhere ;-)
That is a great jig you have built. I wish I would have taken the time to do the same. Then, my x axis would be 850 mm rather than the 842 mm it turned out to be by the time I got it square.
I could be buying a new length for my X as I seem to have scratched hell out off it whilst trying different ways ;-)
Glad you liked the idea of using a Router and Square.
I see you use the same Erbauer Router, I found it to be pretty good value.
I reckon I'll build a jig like yours the next time.
Loving the Videos in your build DazTheGas, keep up the great work, they are sooo helpful.
I really liked your method for squaring up your C-Beam. Nicely done and well edited videos! Cheers from Canada!
Took a bit longer to get last video out but back on track now
Oh poo sticks filmed making the first plate today to find i got .1 deflection in the x axis, so although outside cuts are just shifted left .1mm inside pockets like the bearings are too small....
so guess i sort that out first.
Well its been a long night, upgraded to a leadshine driver and 345oz stepper with no change, new belt and no change. Then with my old ox plates made a mock up of converting the x axis to leadscrew and WOW what a difference, perfect cuts in both X and Y, I can only put it down to the belt flexing a little but as the y has 2 then its holding.
Must be sleep time now, even though its time for work in an hour.
Finally after upgrading the Ox I have finished cutting the Corner Plates for Spartacus video is in Build log as usual and files uploaded.
Now for the X Gantry Plates
Well after a lot of decisions and trial an error, according to solidworks these are the first glimpses of what the X Axis should look like if I get a day to myself to cut them.
One thing I have noticed with my OX and the weight of my spindle is just how much leverage/deflection there is within the X, although the wheels hold the weight well when pressure is applied from top I wanted to take some of the side strain away from the wheels caused by the front loaded weight, if that makes sense. It has also allowed me to space the wheels out further and might add some mini`s in the center.
This is pretty much what I'm going to do with my next machine. It's a simple, but positive way, to remove the spindle twist pivot point. I will probably put a little more distance between the C Beam and the horizontal beam and that will mean an increase in the size of the Spindle mounting plate, height wise, and most likely an increase in the length of the screw, but this should be no problem.
As I've said before, I plan to have yet another beam about 6" higher to attach my vac pipe to, to relieve stress on the Spindle point where the vac will be attached.
I really like this design, well done.
Looking forward to the continuance of the build.
I am thinking of building an ox cnc and while I was looking for inspiration I came across your build. There were three other builds I had in mind from which I found certain parts useful to have in my personal setup. These are: RoverCNC, Ooznest and Robocutter's Super OX.
Using c-beams, I was wondering if by turning the c-beam with the opening inwards (like the RocerCNC / Super OX builds have) the frame would have less deflection / tension when using larger y plates to accommodate the extra x rail as shown in the design above.
Finally finished the X axis and will upload the updated files shortly.
Hi, I was wondering what motor are you using to cut the alum parts, is it speed controled and where do you buy your router bits. I also appreciate the speed & feed info you gave in your video, very informative thankyou;
I have been following your build and really like your ideas. Thanks for sharing!
Hey Daz, I love the build and your attention to detail. That should be a robust and accurate machine when it's done! I too have had problems with X axis deflection on my Ox and I like your solution. I was considering a Sphinx upgrade but now I may have to reconsider and build one of these instead! Are you going to be making the X and Y plate files available to download? Thanks and keep it coming!
can you tell me, in this video you using what brand straight bit ?
I think you'll find he used a normal router bit designed for cutting kitchen worktops.
Just make sure you only take little bites at a time.
Thats totally correct ;-) these are cheap to buy but like Gray said little bites at a time as you can still get deflection on these.
If anyone is wondering where I am at the moment with this build, I am currently videoing the anodizing of the build but slow due to lots of work comits at moment and ofcoarse spending weekends with that special one. ;-)
Great build, I absolutely love the spindle mount! You have totally inspired me to follow in your footsteps Daz, keep up the good work!
Love how you included the anodizing process. Great job!
Hi Daz , been following your videos for a while on the Spartacus Design process & Build + also the Anodising ( Very Interesting ). I also have the very same type 2.2KW WC 80mm Spindle & think your mounting method is just a genius Idea, Much better than the Un-Drilled Ship Anchor they Supply with the Spindle Kit . Keep up the Good Work ! …..
